Unveiling the Neural Circuitry Behind Maternal Response to Infant Cries

Researchers have identified the neural circuitry involved in the release of oxytocin, a hormone associated with maternal behavior, in response to infant cries. Using fiber photometry, the study found that specific populations of oxytocin neurons in the thalamus and hypothalamus are activated by infant vocalizations. The activation of these neurons promotes maternal behavior and bonding. This research provides insights into the neurobiology of maternal responses and may have implications for understanding postpartum anxiety and depression.
